Charge Recycling Sense Amplifier Based Logic: Securing Low Power Security IC’s against Differential Power Analysis

Kris Tiri and Ingrid Verbauwhede

Abstract: Charge Recycling Sense Amplifier Based Logic is presented. This logic is derived from Sense Amplifier Based Logic, which is a logic style with signal independent power consumption that is capable to protect security devices such as Smart Cards against power attacks. Experimental results show that utilization of advanced circuit techniques save 20% in power consumption and 63% in peak supply current and that the logic style preserves the energy masking behavior.
